How the soil spatial scale information impacts on the strategies to achieve the SDG2 aim at 2030

Sustainable Development Goal 2 (SDG2) is an ambitious goal that combines the problems of hunger, food security and sustainable agriculture. Under the Millennium Development Goal (MDG) framework this fell under a broader goal: eradicate extreme poverty and hunger. Soil science, as a land-related discipline, has important links to several of the SDGs, and in particular on SDG2, which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions (eg crop production). The fundamental concept of SDG2 is to achieve double the agricultural productivity by 2030 with a sustainable agriculture. The achievement of SDG2 goal can be evaluated at different spatial scales taking into account the effect of climate change on crop production by means the use of agro-hydrological simulation models. However, the farm scale is the scale where the crop yields are realized, and ...
